Filter by:Active Surveillance (A.S.) of prostate cancer (CaP) is the systematic monitoring of men with low-risk, localized lesions, with curative treatment of those whose tumors show substantial progression. A.S. is different from Watchful Waiting (W.W.), which is the palliative treatment of men with progressive prostate cancer.
RATIONALE: Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. PURPOSE: This phase I trial is studying the best dose of intensity-modulated radiation therapy in treating patients with prostate cancer.
Background: - It is not fully understood why prostate cancer in some men becomes androgen-independent (no longer responds to anti-androgen medication), but genetics likely plays an important role. - Genes contain the hereditary information that is passed down from parents to children. Although everyone has the same set of genes, individuals can have different forms of the same gene. - Differences in genes may explain, at least in part, why some people develop a more aggressive form of prostate cancer than others. Objectives: -To obtain blood samples from patients with prostate cancer to try to identify gene differences associated with progression to the androgen independent state. Eligibility: -All participants participating in NCI prostate cancer protocols. Design: - Participants with prostate cancer are evaluated in the NCI s Medical Oncology Clinic. - Blood samples are collected at the initial visit or at follow-up visits. - DNA (genetic material) and white blood cells are extracted from these samples to be used for genotyping and establishment of cell lines. - Gene variations are correlated with prostate cancer prognosis and prognostic indicators.
This pilot study initiates a research program testing the early technical and clinical performance of a novel procedure for MRI-guided high-dose-rate (HDR) prostate brachytherapy. Testing will proceed in two cohorts of patients. In Arm 1, patients with locally recurrent prostate cancer after radiotherapy will receive tumor-targeted salvage HDR brachytherapy. Arm 1 of the study will be coordinated and closely integrated with a separate concurrent study of MRI-guided prostate biopsy, which will be performed prior to accrual to Arm 1 of this trial (UHN 05-0641-C). In arm 2, patients with locally advanced prostate cancer will receive a boost of prostate-targeted HDR brachytherapy during external beam radiotherapy. This technique will be prospectively evaluated in up to 100 patients. Preliminary data acquired in this pilot study will determine the technical limits of MRI guided HDR brachytherapy and will be critical for the judicious conduct of a subsequent phase II clinical trial. This proposal is innovative in two fundamental ways: MRI-guidance, and specific tumor targeting for HDR brachytherapy. Successful completion of this study will further individualize local therapy, not only for the benefit of the proportion of cancer patients for whom initial radiotherapeutic interventions have failed, but also provide valuable technical and clinical validation that these novel image-guided (IG) approaches are clinically feasible and could be applied more broadly in prostate cancer therapy.
The purpose of this trial is to investigate whether treatment with this new drug will result in lower testosterone levels in men with prostate cancer. At the same time it will be investigated whether the drug induces side effects, and if so, which ones.
A randomized clinical trial evaluating the use of a pedometer and brief exercise coaching in prostate cancer patients treated with androgen deprivation therapy. The investigators want to demonstrate if there are less side effects of hormonal therapy and better quality of life in patients who made regular exercise.
The purpose of this study is to study the difference in prostate cancer between two prostate biopsy techniques, namely end-firing and side-firing. These differ in the angle at which the prostate is biopsied.
RATIONALE: Androgens can cause the growth of prostate cancer cells. Androgen ablation therapy may lessen the amount of androgens made by the body. Drugs used in chemotherapy, such as docetaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. It is not yet known whether giving androgen ablation therapy together with docetaxel is more effective than giving androgen ablation therapy alone in treating patients with advanced prostate cancer. PURPOSE: This randomized phase III trial is studying androgen ablation and docetaxel to see how well they work compared with androgen ablation alone in treating patients with advanced prostate cancer.
Docetaxel and sunitinib will be compared to docetaxel for their effect on CEC/CEP spikes induced by docetaxel in HRPC patients
RATIONALE: Studying samples of blood from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. PURPOSE: This study is looking at genetic susceptibility and the interactions between genes and the environment in patients with prostate cancer.
